I did one of those DNA tests and come to find out I’m 18% Sub-Sahara and 2% Asian (80% European/Central Europe). And I’m of Hungarian decent so go figger the blond hair. Some of my ancestors must have been a bit frisky in certain areas.
I would be VERY careful believing DNA tests. They’re not as accurate as people believe them to be.
